President Donald Trump misleadingly claimed Sen. Bob Corker “gave us the Iran Deal.” Corker, who opposed the nuclear deal with Iran negotiated by the Obama administration, helped craft a bipartisan bill that allowed the House and Senate to review the agreement.

Donald Trump speculates that Shahram Amiri — an Iranian nuclear scientist who defected to the U.S. and reportedly became a CIA spy — was executed in Iran recently “because of Hillary Clinton’s hacked emails.” There is no evidence of that.

In spinning a fanciful tale of how he would have negotiated a tougher nuclear agreement with Iran, Donald Trump betrayed a fundamental misunderstanding of who controlled billions of dollars in Iranian assets that were unfrozen as part of the deal.

Sens. Rubio and Cruz have implied that Iran released U.S. hostages in 1981 on the day Ronald Reagan was inaugurated because Reagan ushered in a new foreign policy. But several experts on the crisis told us the timing was a final insult to President Jimmy Carter, whom the hostage-takers despised.
